环境为CentOS 7.3、httpd2.4.6
一 搭建证书说明：
CA 主机为192.168.29.3 client主机为 192.168.29.100 1 生成私钥 [root@centos7 ~]# (umask 077 ; openssl genrsa -out /etc/pki/CA/private/cakey.pem 4096) Generating RSA private key, 4096 bit long modulus .....................++ ...........................................................................................................................................................................................++ e is 65537 (0x10001) 2 生成自签证书 [root@centos7 ~]# openssl req -new -x509 -key /etc/pki/CA/private/cakey.pem -out /etc/pki/CA/cacert.pem -days 365 You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter '.', the field will be left blank. ----- Country Name (2 letter code) [XX]:CN State or Province Name (full name) []:BeiJing Locality Name (eg, city) [Default City]:BeiJing Organization Name (eg, company) [Default Company Ltd]:Company Organizational Unit Name (eg, section) []:OPS Common Name (eg, your name or your server's hostname) []: Email Address []: [root@centos7 ~]# 3 为CA提供所需的目录及文件（1）所需目录，如果无，则创建
/etc/pki/CA/certs/ /etc/pki/CA/crl/ /etc/pki/CA/newcerts/（2）所需文件
[root@centos7 ~]# touch /etc/pki/CA/serial #序列号文件 [root@centos7 ~]# touch /etc/pki/CA/index.txt #数据库文件（3）
[root@centos7 ~]# echo 01 > /etc/pki/CA/serial #维护ca的序列号 4 在client上进行如下操作（1）创建放置公钥私钥的文件夹
[root@CentOS7 ~]# mkdir /etc/httpd/ssl（2）生成自己的私钥
[root@CentOS7 ~]# (umask 077; openssl genrsa -out /etc/httpd/ssl/httpd.key 2048) Generating RSA private key, 2048 bit long modulus .......................................+++ ...................................+++ e is 65537 (0x10001) [root@CentOS7 ~]#（3）请CA为自己生成公钥
[root@CentOS7 ~]# openssl req -new -key /etc/httpd/ssl/httpd.key -out /etc/httpd/ssl/httpd.csr -days 365 You are about to be asked to enter information that will be incorporated into your certificate request.
